Glass Beaker

Glass Beaker

The Glass Beaker range consists of standard laboratory beakers manufactured from borosilicate glass 3.3, designed for everyday laboratory operations such as mixing, heating, measuring (approximate), and dispensing liquids. Due to their simple cylindrical design and wide opening, glass beakers are among the most commonly used vessels in chemical, biological, pharmaceutical, and educational laboratories.

These beakers are available in a wide range of capacities, from small 5–10 mL sizes to large multi-liter volumes, and feature clear graduation markings, a precision-molded pouring spout, and a reinforced rim for improved mechanical strength. Their chemical inertness and thermal stability make them suitable for routine laboratory heating, stirring, and temporary reaction or holding applications.

Frequently Asked Questions (FAQ)

Q1. Are glass beakers suitable for precise volume measurement?
No. Graduation markings are approximate; volumetric flasks or cylinders should be used for precision measurement.

Q2. Can these beakers be heated directly on a hot plate?
Yes, borosilicate glass beakers are suitable for controlled heating on hot plates or in water/oil baths.

Q3. Are these beakers autoclavable?
Yes, under standard laboratory autoclaving conditions, provided heating and cooling are gradual.

Q4. Do you offer heavy-duty or reinforced versions?
Yes, heavy-wall and reinforced beakers are available for frequent heating or industrial lab use.
